i ADJUSTABLE FOLDING STAND.

Application led July 17,

To all whom it may concern-f Y Be it known that I, ELMER W. BORGER, a citizen of the United States, residing at Palmerton, in the county of Carbon and State of Pennsylvania, have invented new and useful improvements in Adjustable Folding Stands, of which the following isa specification.

This invention relates to adjustable tolding stands and more particularly to devices of this character which can be provided with a sewing machine and so adjusted as to be conveniently used vto sewVY in windows or make repairs to vehicle curtains or the like without removing the curtain from the vehicles or which may also be used as an ironin board and when not in use, collapsibly foiled and conveniently stored.

An object of my invention is, to provide means in a device of the character described which will permit of the convenient sewing et any part of the curtains ot an automobile or other vehicle for installation of windows therein or repair thereto without removing the curtains from the vehicle and which may be also used as a convenient ironing board adjustable to any suitable height and which may fbe collapsibly folded to permit its storage.

Referring to the drawings in which ylike numerals Ot' reference indicate corresponding partsy I Fig. 1 is a. sid-e elevation, with one side reioved showing some parts in vertical section taken on line 1-1 ofv Figure 2, looking in the direction of the arrow.

F ig. 2 is'an end elevation of my device with the parts assembled as shown in Fig. l.

Fig. 3 lis a side elevation with a part broken away for purposes of clearness, showing my device equipped with a sewing machine and with an extended arm thereof in elevated position and in dotted lines with the arm in position for use as an ironing board.

Fig. 4 is a vertical, longitudinal sectional view taken on line 1 -4 of Fig. 2 showing a ball-bearing swivel joint provided in my device.

Fig. 5 is a vertical transverse sectionalview, taken substantially on line 5-5 of Fig.

1 showing a ball-bearing swivel joint provided in my device.

Referring more particularly to' the drawings my invention consists of a supporting frame-work comprised of a pair of Standards 1922. Serial No. 575,700.

Zand 3 and a pair of standards 1 and 5 which are mounted and assembled on a common pivot 6 at their top ends. The standpivot members 11 and 12, the bar 11 joining the standards 2 and 3 while the bar 12 joins the standards e and 5 and operate slidably in the respective channels and slots in these standards. Between the bars 11 and'12 and pivotallyV mounted thereon is a frameworkl composed of transverse bars 13v and 111 braced together by cross braces 15fand 16. Mounted also on'the transverse bar'12 are the substantially vertical pivotal brace members 17 and 18 connecting at their lower ends with the Vmember 12 at their upper ends engaging the pivot pins 19 on the opposite edges of the swinging arm or supporting member 20 and thereby holding the lsupporting member, which is pivotally mounted on one of its vends to the connecting pivot member '6, in operative elevated position. The members 17 and 1S are joined by .cross bars 21 and 22 which act asa strengthening framework between theseV bars and also cause them to operate together; which is likewise the function of the bars 15 and 1G hinged or pivoted on the pivot member 6 is adaptable to angular vertical elevation 0n said pivot to any desired degree. This is acf complished by causing the lbar 12 to Vbe moved up or ldown thelength of the slot V9 in the standards fl and 5 and when the arm 2O lhas reached the desired position of eleva- 'tion the bar 12 is dropped or caused to be seated in one of the slots 10 inthe channel 9, vand thereby supports and locksthe arm 20 in such position. It will be seen from this that the arm 2O may be elevated or lowered at any vertical angle as requiredfupon the pivot 6. A further adjustment of this arm 20 can be accomplished by a similar movement ofthe bar 11 in the slotl 9 provided in the standards 2 and 3 so that the standards 2 and I3 may by moving the bar ll downwardly or up\.vardly in the channel 9, be drawn closer to or distended from the stand ard: 11.- and and will, as their position is changed in reference to standards 4 and 5 result in changing the angular position of the arm for elevation or depression.

Upon the outer end of the arm 2G I have made provisions for the mounting of a mov able and detachable extension 23 upon which I mount in any usual way a sewing machine 2st which can be operated by hand and which is in lined relation to the table or extension 28. rI'he table 23 is in rotatable pivotal engagement with the arm 20, by means of a pivot mechanism to be described hereinafter.v It is also provided with a longitudinal slot 25 which adapts the table 23 to longitudinal movement on its pivot or in reference to the arm 20. rlhe pivot means mounting the table 23 upon the arm 2O consists of a pivot pin or axis 2G provided on one end with a locking thumb nut 27, adapted to lock the table 23 in any position of adjustment ou the arm 20. It is also provided with a socket 28 carrying balls 29 forminfr a bearing for the member 30 carried by the table 23 so that turning movement of the table 23 upon its pivot 25 will result from very slightrforce. This feature of my de fico is of essential importance, because in the operation of sewing for repair or for the installation of a window in the curtain of an automobile or other vehicle, it is desired that, as the sewing operation takes place, the machine will by pull exerted by its needle, properly position itself for the seam 'being made and will therefore when once started need no guiding by the operator although the part being sewed will of course require direction of the operator. In order to provide additional locking of the table 23 against rotation on its pivot I mount pivoted stops Si on opposite edges of the arm 20 near its outer end, so that they may be turned on their pivots and engage the opposite edges of the table 23 and restrain it against lateral movement when it is not desired that it turn on its pivot, as for in stance when a straight seam is being sewed.

By the provision of the supported arm 2O with such an adjustability as is possible in the device as constructed by me I can quiclily sew any portions of vehicle curtains or can insert a window therein and malte any other repairs to the curtain or top requir: 1g a sewing operation, without the removal of the top or curtain.

Further my device is portable and can therefore be quickly brought to the vehicle upon which the repair is to be made, without any unusual labor, owing to the fact that the device is of simple and light construction although durable and Well braced to assure steadiness of position while being operated. It is also a very useful apparatus in a motor or motor top repair shop, especially because of its portability and its adaptability to angular adjustment ot' the arm 2O for vary-*ing'heights Although I have specified m f device to be especially adapted for use in connection with sewing of automobile tops or curtains yet it may be conveniently used in any factory where sewing operations are performed; and in this connection it will be noted that in such factories there is frequent use of an ironing board upon which garments or other sewed articles may be pressed, and for this use my device is well adapted when the table 23 carrying the machine 2Ll is removed from the arm 20.

Another desirable feature is that when not in use my apparatus may be closely folded together in a compact :forni and conveniently stored in a small space.

This folding operation can take place by removing the bars Il and l2 from their position in the notches l0 in the channels 9 on the standards 2, 3, land 5 and moving them to the ends of said channels 9 in opposite directions and closing the standards 2 and 8, l and 5 together thus drawing the arm 20 down into a collapsed position between the standards t and 5, on its pivot 6.

It will be seen from the foregoing that I have provided a novel means to perform the sewing operations above referred to and that these means are of simple construction` light and durable and of convenient Iadjustability for the purposes set forth and which ma j have advantages and results not herein specified. y

Although I have shown and described one embodiment of my invention I do not wish to be limited thereby, for it is obvious that modifications may be made in the construction, operation and organization of parts Without departing from the scope of my in vention.

Having thus described my invention what I claim as new and desire to secure by Letters Patent isf l.
